The Files of Young Kindaichi

Hajime Kindaichi attends a high school with seven rumoured mysteries, where it is believed that anyone who knows about them will be cursed, leading Kindaichi to try and uncover the source of the mysteries.

Inspector Kenmochi, Kindaichi, Miyuki, and Saki go on a fishing tour to Seiren Island from which an eerie sound emanates. The sound is said to be the cry of a siren, a sea creature that draws people into the sea with its voice and devours them.

With the news that the weather will be nice, Kindaichi can leave the island where the sirens are calling. That night, Dr Kageo mysteriously goes missing. Kindaichi and the others search for him on the island and find a secluded boathouse.

Kindaichi and Miyuki are on a family trip to Hakuja Village. At the inn Kindaichi learns from the innkeeper Kyoka that the village has a tradition of worshipping white snakes as messengers of the gods.

Saki takes Kindaichi and Miyuki to an inn owned by his family. At the inn, they meet four art school students, who invite Kindaichi and the others to take part in a bet.

Tachibana, a famous non-fiction writer, throws a party and presents his guests with a cryptic problem, the answer to which will lead them to the draft of his new work.
